Travel cloud pillow

Abstract

A pillow has a knit cover with a crimped siliconized polyester fill. The pillow is sewn into a spheroid shape, which can be adorned with any desired decoration, such as forming the pillow to resemble the head of a character. The outer cover is made of a polyester derived knit matrix in which the weft of the knit matrix has been scratched and raised to produce a nap averaging 2 mm in height. The outer cover is sliver knit on a warp machine to create a unique texture and feel. After knitting, the fibrous yarn is sheared to create a velvet-like pile. The fill encased within the spheroid is 100% siliconized polyester fiber that is created by melt spinning. The fiber has been crimped at an average 9 crimps per inch. The pillow contains no more than 70 grams of fiber per one inch of diameter. This ratio provides the optimal deformation and pressure for a heightened sensory experience.

Claims

1. A method for manufacturing a pillow comprising: knitting a polyester knit matrix on a warp knitting machine, using a base yarn and a pile yarn of polyester; scratching the knit matrix to create raised loops in the knit; shearing the loops to create a nap; stitching panels of the matrix together into a desired shape of a pillow covering; and filling the pillow with a fill of hollow siliconized polyester fibers.

2. The method according to claim 1, further comprising decorating the pillow after the step of filling.

3. The method according to claim 1, wherein a sliver knitting process is used.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) Referring now in detail to the drawings and, FIG. 1 shows the pillow 10 according to the invention. The pillow is a spheroid shape made by sewing several panels of the cover layer 11 together. The knit cover layer is shown in FIGS. 2 and 3. The cover layer 11 is formed from a base yarn 12 with a stretch, such as PBT (polybutylene tetraphthalate). Knitted into this base layer in a sliver knitting process is a fibrous fluffy polyester yarn 13 in such a manner that a looped pile results after coming or scratching the knit. This looped pile is then sheared as shown in FIG. 5 to create cut pile nap.

(10) FIG. 4 shows an enlarged view showing the different textures of the yarns used to create the cover layer. The dark strand represents the PBT base yarn 12, and the lighter strands represent the fibrous polyester yarn 13 that is used to create the pile. The structure of the knitted fabric is shown in FIG. 3, prior to shearing the loops to create the cut pile texture.

(11) The warp knitting machine 20 used to create the cover layer shown in FIG. 6. This is a standard warp knitting machine such as the Karl Mayer HKS 3-S, E28. The machine knits the yarns described above into a fabric that has a unique texture, using a knitting speed of 2000 revolutions per minute. The machine consists of a compound needle bar 1, a closing wire bar 2, a k knockover sinker bar 3, a supporting bar 4, an oscillating brush bar 5 and a pile sinker bar 6. The machine knits base yarn 12 and fibrous polyester yarn 13 into a looped pile knit 9. The creation of such a fabric on a warp knitting machine has not been done until now.

(12) Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
